Dinosaur Body Structure Activity — Marshmallows, Straws and Skewers

We came across a wonderful idea here at U.C. Berkley: The Dinosaur Body to learn more about body structure and how dinosaurs had to be perfectly balanced to stand and move.  I read the paragraphs about the importance of balance and had the kids balance a ruler on their fingers and then add a light head and a heavy head (the heavy head made the ruler tip over and you...

Measuring Dinosaurs Activity

We looked up the length of several well-known dinosaurs, grabbed our plastic models and then went outside to see how long they really were. We chose stegosaurus 30 feet T-Rex 40 feet apatosaurus 90 feet We looked at how long one foot was (we hadn’t done measuring in feet before as we’ve used the metric system up until now) — and then measured out the dinosaurs’ lengths using a 20...

Dinosaur Fossils Impression Activity

At the beginning of our activity we looked at this real fern fossil (from Pennsylvania). We talked about how ferns have been around for millions of years and fossil records indicate they were around well before dinosaurs (we referred back to the chart we have on “what came first” from a previous day.)  Then we went into our woods and looked for different kinds of ferns for making our own...

Geologic Time Line Activity 6

Geologic Time Line Activity

The Montessori teaching albums have an exercise called the “Clock of Eras.” I felt that would not work as well for our family as DD really doesn’t “get” the idea of a clock fully.  I didn’t think it would really teach them the enormity of time as well as a long set of ribbons would… so instead I used the proportions of the clock and made a very long geologic...

The Purple Strip 0

The Purple Strip

For those of you who know much about Montessori, you’ll recognize “The Black Strip.” This is an impressionistic activity that is meant to impress kids with the enormity of time on earth.  Our version was the purple ribbon strip — and it is only 21 feet (as my ribbon ream was 7 yards!).  But it still shows how very little time we humans have been on earth.  I’m showing you...

Timelines 3

Timelines

Montessori uses five “Great Lessons” as an introduction to all topics.  It provides children with a big picture to demonstrate how sciences, art, history, language and geography are interrelated.  This idea resonates well with our learning style.  We did our own version of the first Great Lesson last year and LD still talks about it (and the science experiments and activities that followed). This year we’re off to explore the...

Want to make a “TRASH-O-SAURUS”??!! 2

Want to make a “TRASH-O-SAURUS”??!!

I lost my internet connection this week.  That’s a total bummer since writing on the blog is a major outlet for me since we’re so new to the area (and I know very few people yet). The kids and I had busy, fun week and I hope to start sharing some of our activities later this weekend. We’ve been working on our timeline unit (I’ll explain more soon, though a...

Nature Around the Yard 13

Nature Around the Yard

We had a lot of fun outside yesterday. We caught lots and lots of little tadpoles (and then let most of them go), as well as a couple of 3-inch frogs.  We came across a snake which I’ve tried and tried to identify.  My best guess is that it is a water snake (another book to borrow from the library!). And finally, we found another quite amazing looking mushroom growing...

Egg-speriments! 14

Egg-speriments!

To make our bird unit especially appealing to LD we, of course, had to add in some science egg-speriments! While DD and I were unable to smash our eggs… LD did!!  We’re not quite sure why, but then when he tried it with a second egg he couldn’t break it no matter how hard he tried.  Anyway, this experiment was designed to show how strong egg shells are and how...

And more Egg-speriments! (Eggs and Pollution) 4

And more Egg-speriments! (Eggs and Pollution)

We looked at the air bubbles coming out of this egg when it was placed in vinegar and talked about why the shell is porous.  This lets the growing embryo get oxygen.  We then talked about how since it is porous it can let things through — like acid (vinegar), acid rain and pollutants.  We talked about DDT (how eagles nearly became extinct)– and how poisons, pesticides and so forth...

The Developing Chick-Egg Set 4

The Developing Chick-Egg Set

This summer, I saw a really interesting tool for studying chickens at My Montessori Journey.  It was a chicken hatching set that you can buy for about $35.  It was a great idea, but I decided the kids might get more out of it making their own.  So, earlier this summer at Grams’ house, I printed out some chicken embryo pictures.  One set has the developing chicken embryo with the...

Common Five-Lined Skink 0

Common Five-Lined Skink

We have lots and lots of empty boxes out on the porch. Today it was time to break down lots of them and we found this seven-inch lizard in one of the boxes.  We think it is a ‘common five-lined skink’ — probably the adult version of the smaller, blue-tailed lizards we see all over (the Internet indicates that the blue tails fade as they mature.)

Nature Journals 0

Nature Journals

“This is the best day of my life!”  That’s what LD had to say about the nature journaling we started a couple of days ago.  He was SO excited about drawing all the things we had discovered in the woods that he kept begging for more and more time.  WHAT?!!!  Our son said that?! It’s wonderful to find somethings that is so appealing to him (especially if it involves writing/drawing)....
